Corolla / Matrix 2009-13 :: Code PO302 Cylinder 2 Misfire Detected
Nov 30, 2013
I have a 2009 Corolla S 1.8 with a manual transmission and 30,000 miles. About a month ago the check engine light came on throwing a PO302 code (cylinder 2 misfire detected). I reset the check engine light and drove it about a week before the check engine light reappeared again with the PO302 code. I swapped the spark plugs on cylinders 2 and 3 and reset the check engine light, the PO302 soon reappeared. I swapped the coils on cylinders 2 and 4, and reset the check engine light, the PO302 soon reappeared. I swapped the fuel injectors on cylinders 2 and 3, and reset the check engine light, the PO302 soon reappeared.

2009 corolla 1.8l 155,000 miles. Replaced iridium spark plugs at 100,000
I got a CEL few weeks ago, P0301 Toyota - Cylinder 1 Misfire Detected
Car has been running bad for about 2 weeks now, excise noise on the highway, especially up hills.
Yesterday, I took a look, replaced the spark plug in cylinder 1, same results. Checked the coils using one of those flashing tools, all 4 flashed quickly, with no breaks in flashing. put it all back together, cleared the code, went home.
Took it out for a drive today, and it started running way worse. Checked the CEL, and now I have both P0301 and P0303 Misfire on cylinder 1 and 3. Barely made it home, ran VERY VERY bad.
Got home, and made a video of it. It just kept dying. Check it out here. [URL] .....
Also, when it does run, it almost sounds like I can hear excess air, its hard to hear in video, but doesn't sound right. Maybe air leak? How do I check?

I have a 2009 Corolla with a 1.8 L. I have the misfire code P0301. I have changed the plugs, ignition coil, and fuel injector on cylinder one. It still has the misfire.

2009 1.8 Corolla . I'm chasing an intermittent P0352 code and misfire. Code points to coil pack #2 . Question is, which one is #2 ? I want to swap coils and see if the error follows the coil but I can figure out which cylinder is #2 and since all of the coil wires disappear into a loom, I'm not sure how else to tell.

Went on a trip Sunday, and i saw my engine light come on after i put gas in the car. I pulled over, re-checked the gas cap, and it was fine. Car felt fine.
When i got home, i used my OBD2 scanner, and got the error P0304 Code - Cylinder #4 Misfire. I cleared the error and drove the car some more, no issues.
Yesterday, my wife took the car and she said it was hesitating and sputtering, but the light hasn't come back. I have an appointment at the dealer tomorrow, the car has under 80,000k, so the warranty should kick in.

Wife's car - 2005 Taurus, 6 cyl, 3L, OHV, 83K miles. CEL came on and code came back as "P305 - cylinder 5 misfire detected". The car had been running rough. I changed the plugs, wires and coil. After changing these (and clearing the code) the car seemed to run better for about a week. Today it suddenly started running rough again and the CEL came on with the same code. I'm guessing now this is probably fuel related as opposed to spark related??? As a side comment, the tachometer has been fluctuating as of late as well (again, intermittently).

New to diesel trucks and wondered if this recurring code is a serious problem. I clear DTC and truck will run fine. Might stay off for 2 days or 2 months and same code comes back. Truck seems to run just fine even with service light on.

I have a 2010 Corolla S with 130k miles and started developing what felt like a slight misfire at idle. Dealer suggested change the plugs and if not that try the coils. So I got the wrong plugs givin to me there 5/8s not 14mm. I found a socket that worked and thought the old ones where the same as the new ones.
The 5/8 socket fell right in and knew it wasn't the right size after the plug wasn't tuning. Then I searched and found out there 14mm plugs. So now the socket is stuck inside the metal tube that goes into the head. I tried a locking extensions, long needle nose, hook with a slide hammer, pb blaster, heat, crc freeze off. Even tried spinning it as pulling up with an impact.

A couple weeks ago, my check engine light popped on and I noticed my engine misfire. I happened to be driving by an autozone, so I pulled in and had them check the code. Came back as a misfire on cylinder 4, possibly bad ignition coil or clogged injector. I ran some techron for the next couple of gas tanks, didn't seem to do much, as I would still occasionally get the check engine light.
It has been getting more and more common for it to happen while driving since. Today on the way home from work, it misfired several times in a row and got so bad that I couldn't get above 40mph. This lasted for a minute or two, then cleared up and I made it home without a hitch. Took it back to autozone, same code..Cylinder 4 misfire, probably ignition coil or primary/secondary ignition b fault. I went ahead and bought an ignition coil, came back home and installed. Just took it for a test drive and now I've got the same issue.
I only replaced the one coil that has been throwing a code as misfiring. I did not also replace the spark plug on that cylinder.

My car was shaking badly during idle and the Engine and VSC Off lights came on simultaneously. I took it to a local garage (not dealership) and they said that there is anti-freeze leaking into a cylinder. They said the only way to clean it out/fix it is to first remove the entire engine from the car so it could be worked on. It will cost a total of $2,700. My engine has 141,000 miles on it so they said this may be risky since it is so used. They said for $3,500 they could swap it with an engine that only has 31,000 miles on it (and a 6 month guarantee.) By numbers this sounds like a no brainer (I am assuming?) but I am curious if swapping the engines would be worth it seeing as the rest of the car has still traveled 141,000 miles. I have kept it in good condition and such though. I am also curious if the engine really does need to be removed to fix this sort of problem or it it could be done cheaper.

My daughters '09 Corolla was shaking and misfiring occasionally. When she took it to the shop the mechanic had it for a couple days and after many attempts finally reproduced the issue. After several diagnostics tests they determined it to be a damaged cylinder. We had the option of
1. replacing the engine
2. retooling it
I called around to a couple other mechanics and they told me the same thing. One particular mechanic (no affiliated with Toyota) told us that he had heard this happening on both the Camry and the Corolla. Sound like a manufacturer issues if it's been seen frequently.

I guess misfires are a rite of passage for these vehicles. I purchased it only a week ago. Welcome to Hyundai...
The car has 53k kms. It's throwing P0300 and P030X on all cylinders. There was one instance of P0128. The engine runs smoothly and doesn't seem to down on power, although I have nothing to compare it to. The only performance issue is that it acts as if there is a rev limiter at 6k rpm. It sputters and stops pulling above 6k. Strangely, it doesn't throw the codes under load. The light flashes while it's running steady-state.
I pulled the plugs and they appeared to be in excellent condition with no erosion of the electrodes. The ash is slightly more white than I would expect, making me wonder about it being excessively lean. I called the dealer. They told me that coils are problematic. Replacing the coils made no difference.
That lead me here. I found the thread "Check engine light flashes then stays solid," which referenced the ECM update.
Interestingly, of the codes mentioned on the TSB, the car is having all but the last two.
- P0300: Random/Multiple Cylinder Misfire Detected.
- P0301: Cylinder 1 - Misfire Detected.
- P0302: Cylinder 2 - Misfire Detected.
- P0303: Cylinder 3 - Misfire Detected.
- P0304: Cylinder 4 - Misfire Detected.
- P0128: Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature).
- P0328: Knock Sensor 1 Circuit High Input.
- P0461: Fuel Level Sensor A Circuit Range/Performance.

My Corolla has the P0441 code, but not the typical 0445 code that comes with a loose gas cap. I cleared it and it came back (yes, I checked the gas cap). Googling the issue, I found service bulletin SB 0392-08, which implies the ECM could need to be replaced if the issue is not in the Evap system.

I have a 2009 corolla LE with 81,000 miles on it. Today after I got gas, the check engine light came on. I checked the OBD code and it said P0607. I cleared the code and continued to drive it and it ran fine and the light has not came back on yet. I'm a little worried about driving it on long trips now.
